Be it known that 1, JOHN T. LOGAN, e citizenof the United States, residing at Texerliens, Tenes'heve invented certeln new and usefui'iinprovements' in Apparatus for Tresting the Butt-Ends of Poles, of which the following is c specificstion.

This invention relates to the treatment of Wood, particularly to treatment of the butt-ends poles, and the object is to protide epperstus for treating from four to nine feet, more or iess, of the butt-ends of such poles as are used for telephones, telegre jh, in treating such poles with preserving fluids it becomes necessary to heat the poles or to heat that part of the pole which is to be treated, and it is preferehle to heat only that part of the pole which is to be treated. By the means hereinafter described oniy the parts of the poles which are to be treeted--thet is, the butt-end sectionswill be hosted. These butt-end sec tions are heated to the desired temperature and then suddenly treated with the preserving fluid.

@ther objects and advantages will be fully expicined in the following description, and the invention W'ili he more particularly pointed out in the cisiins. v

I Reference is had to the accompanying drawings, which form a. part of this spplice- 'tion and specification.

Figure 1 is e diagrammatic view of the epperetus used to carry out the objects of this invention. Fig. 2 is e vertical section of the vet which the butt-end portions of the poies are treated with oaths of preserving fluids. Fig. 3 is e plan view of the some in horizontal section.

Simiier characters of reference are used to 'ndiccte the same parts throughout the sev oral views.

The means for carrying out the objects of this invention include a vet 1, a fluid-supply tent: 2, s relief-tank 3, a. steam-boiler 4, a

pump 5, and engine 6, and suitable connectingpipes and valves. The poles 7 are set endwise With'thc butt-ends down in the vet 1. The poles are heated with hot creosote. The creosets is heated by steam-heated pipes 8. Steam is provided for the pipes 8 bythe boiler 4. The pipe 8 is bent and laid on and throughout the bottom of the vet. Bars 9, of iron or steel, are placed between the coils of the pipe 8 to prevent the poles from crushing the pipe. The creosote may helet into the vet 1 in desired quantities by a pipe 10, which has connection with the tank 2. The pipe 10 has sent-off valve 11. Creosote is run into the vet 1 untii the creosote fills the vet to a height of four feet or to any desirable height up to ten feet or more. if more creosote is let into the vet i apipe 13 to the vet 3. The pipe 13 is con-1 valves 12. Any one of the pipes 14 may be opened and the creosote let out of vet i down to the pipe which may be' 'oyzened.

a determined height, the butt-ends of the poles can then be heated to that perticuicr height Without heating the poles higher, no or osote will be Wasted on the poles shove the.

vet with the butt-ends of the poles end. heated 8. higher in the vet than the determined height, but will escape through pipes 14 end 13 to the vet When the butt-ends of the poles have been heated suihciently to expend or rerefy all the air in the Wood-cells in the butt-ends is taken from the vet 1 cold creosote is let immediately and in quick succession as pos sible into the vet 1 from the tank 2. The sir in the Wood celis having been exceeded by the cold creosote therein. The creosote me be replaced in the tank 2 from the reiiehtenit 3 by the pump 5 and pipes 17' and 18. The pump .5 may be driven by the engine 6, and the engine e may be provided with steers from the boiler it The apparatus above described is the kind of apparatus used to cerry out the process described in my pending application filed February 2, M56. it is so erent that other means may be provided for heating the buttends of the poles prior to receiving the treetment in the bath of the coid creosote. Having iuily described my invention, whet Tcleim as new, and desire to secure by Letters Patent, is

1. An eiperstus for preserving end seccontaining the hutt-ends of poles e l serving fluid, coils of pipe iccetect on the e then is necessary, it may be drawn oii through nected to the vet I at various heights by p pes is, Winch are provided with cut-o5.

When the vet 1 is provided with creosote to determined height. The creosote is let into the or butt-end sections, the hot creosote islet suddenly out of the vet i into it relief-tank 3 J by means of at large pipe 15, which is provided Wltlbt valve 16. As soon as the hot creosote tions of 0 cs corn rising en coon-to vet i s {Q o by means of the steam heated pipe coils When the creosote 1S heated, it may rise the hot creosote will now contrectend drew tom of said vat for heating the preserving fluid, means for preventing the poles from crushing said pipe, means for circulating hot steam through. said. pipe, a supply-tank hav- 5 ing a pipe connection with said vat, a relieftank, a large-pipe provided with a cut-off -i 5 provided with an open top vat for containing the butt-ends of poles, a supply-tank, and a relief-tank; coils of pipe located in said vat, bars placed on the bottom of said vat and 4 supportihg-the-poles above saidvcoils of pipe, means for heating said pipe whereby fluid in said vat may be heated, means for sudden removal; of hot fluid from: said vat, and means for delivering immediately cold preserving fluid from'said supply-tank to said vat after 2 5 the removal'o'f hot fluid.

3. In a wood-preserving apparatus pro vided' with anopen-t-op vat adapted to contain the butt-ends of poles set therein and t0 containapreserving fluid; means-for-supplyo inga heating fluid to said vat, a relief-tank,

means for determining the height of the heatingyfiuid in said vat consisting of a series of pipes connected to said vat and provided with cut-off valves and connected to said relieftank, means for heating the fluid in said vat, a large pipe for drawing the hot fluid quickly from said vat into said relief-tank, and means for refilling said vat immediately with cold tan a series of pipes connected to said vat at different heightsand connected to-said relieftank, a large pipe provided with a cut-off valve for quick removal of hot fluid from said vat, and means-for supplying cold preserving fluid immediately to-said vat to take the place of the hot fluid.
